any component on the system board, i.e. cache or memory. The system will require a complete boot when awakened. Since S5 is the shut off state, coming out of S5 requires power on which clears all registers. The Precision workstation T7600 supports all of the above states. Please direct any questions

Dell Precision Workstation T7600
Gentlemen:
The Dell Precision Workstation T7600 contains both volatile and non-volatile (NV)
components.
Volatile components lose their data immediately upon removal of power
from the component.
Non-volatile components continue to retain their data even after the
power has been removed from the component.
The following memory components are present in the T7600:
BIOS Configuration
The BIOS information is stored in two flash ICs, one 8 MByte and one 4 MByte.
These devices are identified as U_BIOS1 and U_BIOS2 on the motherboard.
These
parts contain the boot code and data necessary to take the hardware from a power-
off or low-power state to a state where it is ready to be managed by the operating
system.
No information pertaining to user applications or data is stored in these
devices, however, they do store administrator and/or hard drive encryption
passwords if those features are enabled by the user.
Embedded Controller
The Embedded Controller contains 256 kByte of non-volatile storage space and is
identified as U_EC1 on the motherboard. The EC contains the software necessary to
manage low-level control functions on the motherboard such as thermal control.
No information pertaining to user applications or data is stored in the U_EC1 device.
The embedded controller also contains 8.25 kBytes of volatile memory space.
The
contents of this memory space are lost when power is removed from the system.
PCH CMOS
The PCH, identified as U_PCH, contains a 256 Byte battery-backed memory.
This
memory contains custom configuration data required by the BIOS to boot the
system.
It does not store passwords or other user level data.
The contents of this
space are lost, after several minutes, if the coin-cell battery is removed from the
motherboard.
Ethernet Controller
EEPROMs
The Ethernet Controller EEPROM is identified as U35 on the motherboard. It is a 2
kbit device.
The Ethernet Controller EEPROM stores driver information and the
system MAC addresses.
It does not store password, IP address, domain name,
system ID, or similar information.
